Application led May 4, 1908. Serial No. 430,840.

To all whom it may concern:

Be it known that I, SIMON B. MiNNicn, a citizen of the United States,residing at Landisville, in the county of Lancaster and State ofPennsylvania, have invented certain new and useful Improvements inStreet-Crossings, of which the following is a specification, referencebeing panying drawing.

My invention relates to improvements in street crossings, of that classwhich are constructed of cement or concrete, and protectedl andreinforced by metal or other suitable material.

The objects of the invention are to produce a durable, cheap andefficient crossing that may be readily constructed and laid, and that isso designed that heavy vehicles will not crack or crumble the edges inpassing over it, and it may be level or slightly rounded to conform tothe grade of the street from curb to curb.

Another object of the invention is that it may be laid in one continuouspiece from curb to curb, or as a cover for a culvert, etc., and that itwill afford a smooth surface easily kept free from dirt and snow.

The invention consists in certain .novel features of construction andcombination of parts that will be fully pointed out and claimedhereafter.

Similar reference figures designate correspending parts in all theiigures of the drawings, and it is fully understood that while I havedescribed my invention as herewith ustrated, I do not confine myself tothe eX- act design as shown, as slight changes may be made in theconstruction without departing from the spirit of the invention.

In the drawings Figure 1, is a plan view of my crossing spanning astreet from curb to curb. Fig. 2, is a side elevation on the line y-fyof Fig. l, showing the method of securing the wearing and protectingplates. Fig. 3, is a cross sectional view on the line -*x of Fig. l,showing the side irons, stay-rods and protecting plates. Fig. 4., is apartial sectional view showing a modified form of side irons. n Fig. 5,is a artial side elevation showing a form of endpextension to bridge agutter. Fig. 6, is a partial side elevation,

showing the crossing spaced from the curb to form a gutter and bridgedto a plate. Fig. 7, is a surface ofone of t the side walk by artial viewof the inner e U-shaped side irons had therein to the accoml Ishowinffthe end bar for su ortiiiO' the i C C gutter plate.

Referring to the drawings, l, indicates Lne curbing; 2, the side walk,and 3, the roadbed.

'Ihe invention consists in the two side irons e, herewith shown asU-shaped, but which may be of the forni shown in F 1g. 4, or

any other suitable shape, and 'which extend from end to end of thecrossing, and in a parallel relation to each other, and which may beextended by splicing to reach from curb to curb, or within a shortdistance of -said curb in one continuous piece. Said side irons areplaced parallel to each other and at tlie required distance apart withtheir anges extending inwardly, and they are firmly held together by thestay-rods 5, which are passed through the bolt holes in the sides ofsaid irons.

The stay-rods 5, are screw-threaded for a portion of the way upon eitherend thereof and provided with the inner nut 6, screwthreaded thereon,designed to forni a shoulder to engage the inner surface of the sideiron and serve to keep said side irons spaced apart, while the ends ofsaid stay-rods 5, extend through and beyond said side irons. To theouter surface of said side irons are detachably secured the wear orprotecting plates 7, which are of the same length and width as the outersurface of said side irons 4, and which are provided with bolt holesregistering with the bolt holes in said side irons and adapted to beretained in contact to said side irons by the nuts 8, which arescrew-threaded upon the ends of the stay-rods 5, thus retaining saidside irons 4L, and the wear plates 7, in a rigid manner to the stay-rods5, and to each other, while the space between the inner sides of saidside irons 4, is filled with the concrete or cement 11, which when setmakes a very strong street covering, and by the use of the U-shaped sideirons 4, the upper or exposed corner of the block is fully protectedfrom being broken away by vehicles, wheels, etc., and to more fullyprotect it, is provided the detachable wear plate 7, which when itsupper edge is worn away, may be turned or reversed so as to expose afresh edge to the wear of the vehicle wheels.

To afford a bridge for a gutter I provide the U-shaped bridge strips 9,shown in Fig. 5, which are secured to the ends of the side irons 4, andaord amretainerand supportjfornthe extension of the cement block 11; orthe crossing may be spaced from the curbing and joined thereto by aplate 10, as shown in Fig. 6.

The device is so simple and will be so readily understood from theforegoing description, that it will be unnecessary to explain itsworkings further.

W hat I claim as new and desire to secure by Letters Patent is 1. In astreet crossing of the class described, U-shaped longitudinal sidesformed with an edge protecting flange, stay-rods securing said sides ina spaced relation, one to the other, a wear plate removably secured tothe outerysurface of said sides and adapted to protect the edges of saidsides.

2. In a street crossing of the class de= scribed, comprising` arectangular block eX- tending from curb to curb, rotecting U- shapedside plates placed witi their upper edges flush with the upper surfaceof said block, 'wearing plates secured to the outer surface of saidsides with their upper edge flush vwith the upper edge of said sides,stayrods embedded into said block and having their sides secured to saidprotecting sides and said wearing plates.

In testimony whereof I affix my signature in presence of two witnesses.
